Swelling in diabetic patients is not necessarily advanced. Early kidney disease can also cause swelling, early cardiac dysfunction and lower limb thrombosis can cause swelling in diabetic patients, and hypothyroidism can also cause generalized swelling. However, when swelling occurs, it must be a problem of the body, so we must promptly check the nail function, heart, liver and kidney, find the cause and treat the swelling in time to avoid serious consequences. If you don’t take the swelling seriously and sit every day, the swelling will definitely be more powerful and serious complications such as heart failure and kidney failure will occur, which is really advanced and very difficult to treat, and even life-threatening.
